Frosty relations between the U.S. and Pakistan - which led to Pakistan closing its border to Afghanistan-bound truck traffic- haven't helped, either.
The Pentagon is increasingly relying on parachute drops of fuel and other supplies to bases in remote parts of Afghanistan, and as Nathan Hodge of the Wall Street Journal reports, the military estimates such deliveries are spiking the ultimate price of a gallon of fuel to as much as $400 per gallon.
"We're going to burn a lot of gas to drop a lot of gas," Capt. Zack Albaugh, a California Air National Guard pilot with the 774th Expeditionary Airlift Squadron, told the WSJ. Albaugh would be at the controls of a C-130 cargo plane that drops pallets of food, water, ammunition and fuel by parachute to troops below.
Avoiding the dangers facing truck convoys on the ground, the Pentagon has relied more and more on air delivery of supplies. Six years ago, about two million pounds of supplies were air-dropped to troops in Afghanistan. Last year, that amount was about 60 million pounds. Estimates are that this year the total will be about 90 million pounds.
